Three common challenges in carbon fiber processing.
Carbon fiber boasts outstanding properties such as high compressive strength, lightweight, low friction resistance, and high specific heat capacity, making it applicable in every manufacturing industry. However, its unique structure and complex processing characteristics pose a series of challenges for machining. If these issues are not adequately addressed, products can easily incur significant costs, resulting in substantial losses over minor issues. Below are some common challenges along with potential solutions.
Common challenges include:
The material tends to delaminate, resulting in block-like breakage or tearing, with the most severe case being complete product failure.
CNC cutting tools wear out quickly. Using blunt tools for machining can further damage the workpiece. In finishing processes, the shape and specifications of the cutting tool may change, affecting the final product's dimensions and shape. Moreover, for tools that require precise diameter specifications, tool wear can result in unstable hole and groove dimensions.
Short tool life and low wear resistance increase the machining costs of products. To improve production efficiency and maintain precision in terms of shape and specifications while controlling quality and reducing machining costs, a series of changes must be implemented.
While carbon fiber has high tensile strength, it is also sensitive and prone to breaking. During machining, using insufficient force is ineffective, while excessive force can cause cracking, which complicates the process. To address the above issues, focusing on the cutting tools is crucial. Under the same parameters for drilling and laser cutting depth, experimenting with different materials, sizes, and shapes of cutting tools on carbon fiber can yield insights into their effectiveness. Continuous experimentation with controlled variables can help find the optimal cutting tool. Factors such as drilling amplitude, time, and environmental temperature will also affect the machining results, all of which need careful consideration.
